Be it known that I, RICHARD SCHNEIDER, a citizen of the United States, residing at Flushing, in the county of Queens and State of New York, have inventedcertain new and useful Improvements in Shutters, of which the following is a specification.

The main object of this invention is the provision of ashutter of simple construc, tion, which may be readily attached and in-' stalled and easily manipulated. I

The above and other ob'ects will become apparent in the description below, in whlch like characters of reference refer. to like named parts in the drawings.

Referring briefly to the drawings, 1

Figure 1 is a front elevational-view of the shutter structure casing assembled.

Figure 2 is a partial side ele'vational view, partial sectional view of the same. I

Figure 8 is a perspective viewof one of the shutter elements in detail.

Figure 4 is a plan view of'th'e'shutter when the elements are in an open position.

Figure 5 is a transverse sectional view taken substantially through the center of the same. i 1

Figure 6 is a view similar to Figure & bu showing the parts in a closed position.

Although the original purpose of this invention was for controlling heat it has been found useful for many like purposes and therefore may be used with or without the outer casing in which it is shown. i

This casing is comprised preferably of a thin walled metallic box 12, an oblong rec tangle in shape, supported by hangers 17 at the upper rear corners and provided with an inlet 11 adapted to be connected-with any convenient supply of heat.

Extending centrally outward from the front wall is a hollow 't'rusto-conical member 13, its base being outermost, the same conininnicating with the interior oi the casing through the opening 14.

Fixed to the inner sides of the front wall is a flanged band 24- ,formed with a cover 7 plate 25 spaced parallel with the front wall and having a central circularopening 26.

Seated against the inner side of the plate 525 is a disc 27 having an opening 28 registering with the opening 26 and on the disc is a ring 18 projecting towards the "front wall of the casing 12, this ring having an annular groove 21 in its periphery into which extend the raised elements of the brackets22,

-and an arcuately curved opposite i edge as shown in F1gure-3."

of Z shaped cross section secured to the I front'wallof the casing within the band 24," these b-racketscentering and supporting the ring and disc in an obviousmanner. i

The interior of the ring is provided with gear teeth and is in elfect an internal gear capable of being rotated by a handle 15 operatively extending through an elongated, arcuate slot 16 in the front wall of the casing as best shown in Figure 1. g 3 p Set in a circular row 'lII'lillG cas'fing'-12, at uniformly spaced intervals are'pins 19 upon which are pivoted shutter elements 20, these shuttershaving a straight edge on one side or outer- These shutters are flat and smooth onboth I sides except at their pivoted en.d,-which is increased in thickness as at23 and provided with peripheral teeth engageable in the teeth of the ring 18 in such. manner that upon operating the handle 15, the"shutters may be simultaneously opened as: shown in Figure 4 orclosedas in Figure 6, with re spect to the opening 28, indicated by broken lines thus providing: eithera clearfpassage the-rethrough or completely closingit. Having thus described-my invention, what I claim as new and desire to secure by Letters Patent, is I j In a'heat controlling shutter, the combination with a plate having an orifice,-a frustoconical member integral with saidplate'lead. ing outwardly from the mentioned orifice, a

circular casing having a corresponding orifice in it-s'rear wall secured to said plate, an internal gear rotatably mounted in said case, ing, an annular flange formed with said gear, said flange havingan opening. disa single means for mannally rotating said gear, said means extending outward through said plate, a plurality of flat level shutters pivoted in spaced relation. to said plate, said shutters when open presentii'ig a clear unob 'structed passage through said plate, cas ng sectors operatively .ineshing with .the tooth offsald nternal gear and being pivoted 1nsaid plate to operate within said casing.

In witness whereof I'aflix my slgnature.
